Filner, who said he's been through the AIT machine but not the pat-down, said he can relate to the complaints he's getting from constituents.

"It feels embarrassing," Filner said Friday. "It feels like you've been violated so I understand what people are going through and I applaud Mr. Tyner for making a case out of it."

Filner is concerned about what airline passengers are giving up in exchange for security.

"I think TSA has finally crossed the line here in showing we are giving up too much liberty to protect ourselves," said Filner.

On Wednesday, TSA Administrator John Pistole told a U.S. Senate Committee that the agency is close to announcing a possible deal exempting airline pilots from the AIT machines. Some pilot groups have raised concerns about health concerns.
